Enum Type

[levan Dvalishvili <ad...@amostudio.com>]

Hi All! 
I am need to this mailing ,a s a fact this is my first question here .. 

I am working on a project and would like to use ENUM as an attribute on my
bean  like this :

------------------ SAMPLE CODE ------------------------
public class Shipment  implements  Serializable{
enum ShipmentStatus{notShipped("Not Shiped"),
			  onTheWay("on the way"),
			  arrived("Arrived");

      private String value; 
       
      ShipmentStatus(String newValue) {
          value = newValue; 
      } 
      
      
      ShipmentStatus() {
          value="NOT SPECIFIED";
      } 
      String getShipmentStatus() { return value; } 
   }
    
    private ShipmentStatus Status;
    private Date departureDate;
    private ShipmentStatus Status;
    private Date ArivalDate;
 etc .....
}
---------------------- END OF SAMPLE CODE --------------------------------

I am working into IBATIS as I go ..., and would like to ask if this way will
work with the mapping? Do I have to write a custom type handler? 
I also have ac corresponding enum on database side (DB is mySQL) Has
anything like that been done yet? Is this a right way of doing it or should
I just forget about ENUM  and just use string?
Best regards
And thanks for creating such a great product

Levan,

As a first time poster let me inform you on a great source of  
information.  Below is the archive of this alias.  Please search  
there before posting new questions.

To answer your post...

Yes,  This is fully supported in ibatis.  You will need to create a  
CTH(custom type handler). There is a wiki post about this.

+Enumeration

On a side note I would not suggest naming you enums like that.  Other  
people might get them confused with a method name.  I would suggest  
FULL CAPS for enum names. Just a good convention :)
